Playing behavior can improve the movement and social skills of mammals and facilitate the development of social relationships. To investigate the playing pattern of Trachypithecus francoisi during individual development, data of playing behavior were collected from two groups of captive immature T. francoisi in Nanning Zoo (Guangxi) using focal animal sampling and all occurrences recording methods. The results indicated that fight play accounted for on average 14.4%~16.9% of total playing time, 3.6%~13.6% for chase play, 48.6%~57.0% for solitary locomotor play, and 20.8%~25.0% for object play. The play frequencies were varied between male and female juveniles. Male juveniles exhibited significantly higher frequencies of fight play and chase play than female. Moreover, male juveniles were more active in social play than female. These results support the motor training hypothesis that animals play for physical exercise or development of physical skills. Both immature male and female T. francoisi preferred to play with male juveniles rather than female. The patterns of playing behavior would change along with individual development. Infants exhibited significantly higher frequencies of solitary locomotor play and object play compared with juvenile individuals.
